How do I start (and maintain) a fulfilling bromance?

Hey guys! I (19M) have struggled my entire school years yearning to be a part of a boys' group, and do all sorts of aawara things together that I see guys usually do. Forming friendships with women was relatively just easy for me (and I'm grateful for that, no doubt); however as a guy there's always this part in you that wants your bros to be there for you when you need them and vice-versa which is irreplaceable by any other sort of connection. Trust me, I'd tried so hard to fit in the boy groups throughout school (and now in college, I am a freshman) but almost always I felt as if I had to mask certain parts of myself to integrate in the group - I'm neurodivergent, so if kinda of acts as the cherry on top. Also belonging from an actual middle class background, I can't sustain the lifestyle of the nashedi type or the bougie type. I'm a very accepting person (side effects of having a lot of female friends), and I usually am the last person to comment or shame a person because of their preferences in regards to how they present themselves, what they like/dislike,etc. - basic human decency. It also stems from the fact that I personally experienced a lot of negative judgement from my guy classmates - one instance, for example, is when I was just normally laughing in the class where one of my guy friend points out that why was I covering my mouth while laughing, and "tu ladki hai kya jo aise Hans raha hai?" - as if being a woman is a degrading thing and associating with them makes your "inferior"; not to mention how a low IQ & EQ statement it is to make. Anyways, this is only one of the many instances, though I wasn't bullied outright for some of my "feminine" ways of behaving (listening to your friends attentively when they tell you something, showing empathy for others, taking pictures with a smile on the face are somehow things to be done only by women???), I certainly did face passive aggressive exclusion by guys because of so. I really, really yearn to make good guy friends - and confiding your wounds like these is a quite vulnerable and risky thing to do - and thus I find myself stuck in a negative action loop. Not to mention, I'm quite awkward when it comes to physical affection - I've seen guys bond via showing physical affection towards each other (hands on shoulder, smacking butt, maybe even giving a kiss on the cheek) and since I didn't have any brotherhood growing up, how to naturally show physical affection is something I'm really careful around with guys now, because neither do I want them to think I'm not interested in furthering our friendship nor do I want to come across as a perv. Ts was half a vent, and also a half request for other guys who are/have been in the same boat as me before, to please provide some advice as to how can I form good male friendships. I really value what I am, what men are and what healthy, vulnerable friendships with them feel like (especially that feeling that you've a safety net of your boys to fall back on when life gets tough). I'm in law school currently so I'm much more concerned if I'd be able to do it in the first place 🥲. Guys please assist, and if you made it till here, thank you so much for reading! 🫶 Adios :)
